This study raises a concern for the use of practice-tests for low-level learners whose English grammar knowledge is limited. TOEIC preparation is still useful and could be an effective way of improving learners’ listening/reading skills and their grammar knowledge, but the materials and approach used for grammar instruction definitely make a difference. The presentation of target grammar points in a sequential and organized fashion seems to be an important factor for teaching TOIEC grammar to low-level. It is something teachers and curricu-lum coordinators should reconsider when they choose textbooks and design TOEIC preparation courses. Separate grammar review should be incorporated if practice-tests are used. Or, maybe using topic-based textbooks is a better choice for low-level TOEIC preparation courses.
